Hello All, in order to write an applet using JOGL I need a *SIMPLE* example using no special libraries etc. Would some kind person please supply one. I can write JOGL non applet programs.

Andrew, I think you have misinterpreted the tone of the OP's request. To the OP: but Andrew's advice to forget applets and use webstart for this is almost certainly correct. Personally I don't know much about JOGL (except that it runs very badly on my machine), but it /needs/ add-on libraries and I don't think that is (or should be) possible for an applet[*]. ([*] maybe if it's signed ? But then you are definitely not talking 'simple'...) -- chris On Feb 16, 5:29 am, "Chris Uppal" <chris.up...@metagnostic.REMOVE- THIS.org> wrote: > ...Personally I don't know much about JOGL (except that > it runs very badly on my machine), but it /needs/ add-on libraries and I don't > think that is (or should be) possible for an applet[*]. I managed to get JOGL running as an applet, only after the JOGL binaries were installed, and then only once each browser session. The problem seemed to be that JOGL was calling functionality that is not available to applets (System.exit() AFAIR), failing, and failing to clean up after itself. Further JOGL applets (or the same page refreshed) would have the applet fail to start. > ([*] maybe if it's signed ? But then you are definitely not talking > 'simple'...) I tried supplying the classes and natives to the applet, could not get it to work, signed or otherwise. OTOH - a web start launch is simplicity itself. The JOGL libs. are available as a JWS <component-descriptor> that the developer can simply link to from within their own JNLP.

Web start launches a free floating frame or applet, but it can be launched using a JNLP (web start) file linked *from* a web page.

I will continue to do my bit to promote this wonderful deployment technology, from suggesting it every time I here the word 'applet' or any application deployment suited to JWS, to putting up complete examples of use of web start and the JNLP API. > Are you the AndrewThompson64 user you mention on your webpage above? Yes. I would link to my posts on usenet, but those Sun posts are generally more specific to web start. >..I'm > just curious.

Hello all, I still have not got an answer to my previous question: if I want to put a java application onto my web page (for all to run) using web start what do I need to do? Obviously this would be wonderful as I wouldn't have to convert the application to an applet first.

I partly misread your earlier question.. > >..Obviously this would be wonderful as I wouldn't have > > to convert the application to an applet first. Aha! I thought you were talking about converting an applet, and I wanted to get that sorted first. OK.. > You'd have to create a jnlp-file. Yep. Now I know you are 'on board' with the idea of launching via JWS, I hunted down the relevant info. on my javasaver site.. Here is an example lauch file.. <http://www.javasaver.com/testjs/jws/04/glclock.jnlp> The content of that JNLP file is.. <?xml version="1.0" encoding="utf-8"?> <jnlp spec="1.0" codebase="http://www.javasaver.com/testjs/jws/04/" href="glclock.jnlp"> <information> <title>Preview - GLClock</title> <vendor>SaverBeans - JDIC</vendor> <description>Preview of the GLClock SaverBeans Screensaver</ description> <description kind='tooltip'>GLClock Preview</description> <icon kind="splash" href="sb-jws-splash.gif" width="450" height="250" size="16075" /> <icon href="smallbean-32x32.gif" width="32" height="32" size="1044" /> <offline-allowed/> <shortcut online="false"> <!-- create desktop shortcut --> <desktop/> <menu submenu="SaverBeans Screensaver"/> </shortcut> </information> <resources> <j2se href="http://java.sun.com/products/autodl/j2se" version="1.5+"/> <jar href="glclock.jar" size="4917"/> <jar href="saverbeans-api-dev.jar" main="true" /> <jar href="other.zip" size="4246" /> <extension name="jogl" href="https://jogl.dev.java.net/webstart/ jogl.jnlp" /> <property name="jnlp.saverName" value="GLClock"/> <property name="jnlp.config" value="/glclock.xml"/> </resources> <application-desc main- class="org.jdesktop.jdic.screensaver.ScreensaverFrame"> <argument>org.jdesktop.jdic.screensaver.clock.GLClock</argument> </application-desc> </jnlp> Most of the resource mentioned there can be seen in the directory listing for .. <http://www.javasaver.com/testjs/jws/04/> ..they proabably amount to around 100Kb, but the bulk of it is coming straight off the JOGL area of the JDIC site. Ironically, amongst all the fluff from my site (icons and such) the smallest part is probably the actual screensaver jar that all this is meant to display. The gjclock.jar is less than 5Kb. Note there were some package changes last year(?) to the JOGL api., and I suspect they must have provided a new URL for the repackaged classes, check the JOGL/JDIC site for latest information. HTH Andrew T. <Andrew mentions JWS> > Interesting page, thanks. JNLP isn't widely enough known about/used, > methinks. Really? Sometimes it seems to me that fully half of Andrews postings tell folk how JWS is the solution to their problem. I find this frequent advocacy of JWS rather hard to miss. (the other half of Andrew's postings are admonishing spammers) (I wouldn't be at all surprised if some postings do both :-) > <Andrew mentions JWS> > [quoted text clipped - 4 lines] > tell folk how JWS is the solution to their problem. I find this frequent > advocacy of JWS rather hard to miss. I must admit, I am still not entirely sure that Lex was not simply 'taking the piss'*. * Is that an expression known anywhere outside Australia? TTP -> making fun of a person/people. Andrew T. >> <Andrew mentions JWS> >> [quoted text clipped - 7 lines] > sure that Lex was not simply 'taking > the piss'*. Nope, I wasn't extracting the pee-pee - I meant what I wrote. When I said "JNLP isn't widely enough known about/used, methinks", I meant it in a general way, and not in the context of myself, or even this newsgroup... it's not like I've just found out about JNLP, but I've not looked at it much before, either. lex > I must admit, I am still not entirely > sure that Lex was not simply 'taking [quoted text clipped - 3 lines] > outside Australia?

There is also "to piss off", "to anger or annoy"; "pissed", "angry", "annoyed", or less commonly, "drunk"; "a pisser", meaning in some regions, "a really good time" or "an interesting thing"; "piss off!" as a command, "go away!"; "piss-poor", "really penurious" or "incredibly bad"; "pissing in the wind", "engaging in futile effort"; "pissing on an electric fence", "urinating on an electric fence" (a metaphor for innocently causing oneself pain or harm); "pissing contest", "a conflict over an insignificant issue"; "piss test" (also "pissing in a cup", "pissing in a jar"), "urinalysis to detect illegal substance abuse"; and likely others with which I am not familiar. I have never encountered "taking the piss" in U.S. parlance. What a pisser, eh? - Lew > In the U.S., "to take a piss" means "to urinate". "To piss" in that sense is almost certainly universal, since it pre-dates the expansion of English across the world. But I think the specific form "take a piss" is a US-ism. In British English (B.E. hereinafter) it would be "have a piss"; I don't know about the other English speaking nations. (BTW, when I say "British English" I mean English as I hear and see it used today -- which is by no means representative of all British subcultures.) > There is also "to piss off", "to anger or annoy"; Same in B.E. But the shorter form, "pissed", meaning annoyed, is not (although it may be creeping in). Incidentally, I gather that in US English "ticked off"/"ticked" is roughly equivalent to "pissed off"/"pissed" -- that /doesn't/ carry through into B.E, where "tick off" is a verb meaning "reprimand", and "ticked" is something that a clock has done. > "pissed", "angry", "annoyed", or less > commonly, "drunk"; Nearly always in B.E "pissed", as an adjective, means "drunk" (inebriated with alcohol -- other substances/causes don't count). > "a pisser", meaning in some regions, "a really good > time" or "an interesting thing" Completely unknown in B.E. (and therefore highly likely to give offence). "Pisser" in the opposite sense, meaning some unwelcome fact or occurrence, is creeping in (as is "bummer"). >; "piss off!" as a command, "go away!"; Common in B.E. > "piss-poor", "really penurious" or "incredibly bad"; Reasonably common, but only as a US import (I think). > "pissing in the wind", "engaging in futile effort"; Would have to be "pissing INTO the wind" to make sense in B.E; it's not a common-enough phrase to have lost its roots as a pungent metaphor. Though, now I come to think of it, I'm sure I've heard "pissing DOWN the wind" too -- I'm not sure what special sense, if any, that has. To me, here, today, it seems to suggest wasteful (as distinct from futile) activity. > "pissing on an electric fence", > "urinating on an electric fence" (a metaphor for innocently causing > oneself pain or harm); Unknown in B.E, but would probably be understood as a one-off metaphor. (Although I'm not sure that the implication of an /innocent/ mistake would come across -- it might be understood as causing oneself harm through stupidity). > "pissing contest", "a conflict over an > insignificant issue"; Similar meaning in B.E. But the sense is more of a pointless /competition/. Usually understood as a contest where the real issue is dominance and status, rather than the (trivial) issue which is the nominal point of the contest. As in masculine head-butting, or ego-driven competition between rival companies (the name "Oracle" springs to mind ;-). > "piss test" (also "pissing in a cup", "pissing in a > jar"), "urinalysis to detect illegal substance abuse"; and likely others > with which I am not familiar. Never heard that here -- but then we don't often talk about dope tests except in the context of professional sport (where they tend to be called just "dope tests"). > I have never encountered "taking the piss" > in U.S. parlance. In B.E. it can also be used for something like "abusing the system for gain", or "taking unfair advantage of what's offered". The underlying sense is "making a mockery", so it's not far off the usual meaning, but there is no suggestion of (unkind) humour, and the tone is definitely disapproving. A topical example: most Westerners see Japanese "research" whaling activities as taking the piss. -- chris > Hello, does that mean that if I have a JOGL "application" (containing a > "main()") I can get this to run in my web page?

Perhaps not, I was unaware of the changes mentioned by RGB (to be honest - it had been more than a year since I had carefully looked at JOGL).

It has been tested and should work on any OS/CPU combination supported by JOGL with a Java Runtime Environment version 1.4.2 or later installed into the web browser. Here is an example of the standard Gears demo running as an applet:" Not knowing jogl I have no way of telling if what the page refers to meets your requirements of "simple" and "no special libraries" but the wording strongly suggests that this may be the case. > Googling for jogl reveals > [quoted text clipped - 7 lines] > installed into the web browser. Here is an example of the standard Gears > demo running as an applet:" Interesting. For me, what seems to happen is that the applet displays the usual applet-loading screen, while it downloads something (presumably the JOGL DLL, since it takes ages), and /then/ puts up a "do you want to trust XXX?" popup -- which I refuse (naturally). The applet then closes down. Ideally, I would get the trust prompt /before/ (or at least while) the long download was happening. I haven't yet looked to see if the DLL is still in any sort of cache anywhere on my system (I hope not). I would like to know what the security architecture is here. Presumably it's something like jogl itself can be downloaded (if I accept it) if it /has/ been downloaded then unsigned applets can use it. If so, then I'm pretty unhappy about it.
